2.5 USB Connector
The USB interface supports plug-and-play functionality, which enables users to con -
nect or disconnect a device at any time without powering off the system. Equipped
with four USB connectors, UNO-2484G provides complete plug-and-play and hot-
swapping capabilities for up to 127 external devices. The USB interface can be dis -
abled in the system BIOS. Additionally, the provision of four USB ports complies with
USB EHCI, Rev. 3.0. (Refer to Appendix A.5 for pin assignments.)
2.6 RTC Battery
UNO-2484G has an RTC battery to ensure that the BIOS and system clock settings
are retained even after brief power disconnections.

2.7 Power Button / Power Management
Press the “PWR” button to power on or power off the UNO-2484G(ATX type). The
UNO-2484G supports the ACPI (Advanced Configuration and Power Interface).
Besides power on/off, it supports multiple suspend modes, such as Power on Sus -
pend (S1), Suspend to RAM (S3), Suspend to Disk (S4). In S3 and S4 suspend
mode, the power consumption can be less than 2W, which meets Energy Star
requirements.
2.8 Reset Button

2.9 PCI Express Mini Card Socket
The UNO-2484G single-stack model supports one full-size socket for PCI Express
Mini Cards. The (MINI1) interface supports USB, PCIe, and mSATA signals and can
automatically detect the device type to provide the required support. This function
can be accessed via Wi-Fi, 3G communication module, or mSATA SSD.
The UNO-2484G double-stack model combines a single-stack model with a UNO-
2484G-EKAE extension kit. In addition to the Mini PCIe slot on the first stack, the
double-stack model also supports three additional full-size PCI Express Mini Card
sockets on the second stack. The MINI1 interface on the second stack supports USB
and PCIe signals. The MINI2 and MINI3 interfaces only support PCIe signals.
Note! In addition to the Mini PCIe (MINI1) socket, the system features a SIM
card slot for supporting 3G/LTE functionality. However, users are
required to install a 3G/LTE mini PCIe module to enable this function.
